La Glorieta de Cuatro Caminos, in the north of Madrid, is the square where the streets of Bravo Murillo, Santa Engracia, Raimundo Fernández Villaverde and the Avenida de la Reina Victoria all come together.
The Cuatro Caminos metro station, located in the square itself, allows you to reach many parts of the city thanks to the 3 lines that run through the station: Line 1, Line 2 and Line 6. This makes leaving your car in one of the car parks that you can book online a great option for then getting around Madrid using public transport.
Around La Glorieta de Cuatro Caminos there is also an important shopping and administrative area, which you can easily get to within a few minutes' walk from where you parked.
